Open Port Checker Status

isOpen.net allow check all ports (TCP) for 'open' or 'closed' status with label name service (Ports Scanner) online

Security

Open ports on a server are a security vulnerability that can potentially allow a hacker to exploit services on your network. If those services are deprecated or unpached, a hacker can easily take advantage of the system by running a simple port scan to discover services runing in your ports. It’s important that you understand some basics about port security and only allow conection to necesary ports adding fireware rules to access only from friends (identified) IP address.
